Blogs, LabVIEW Blog
There is a very good device named FT4222H from FTDI Chip which can be used for multi-interfaces like GPIO, I2C, SPI, Interrupt.  The nicest thing is you could access all those communication protocols directly using LabVIEW.  Generally speaking, if you work with a controlling application where your end-device uses such protocols, you could use this device to communicate with the end-device and make the life easier and design would be low cost too (device costs only $2.30).
